+# - E22-900M22S LoRa module (bare SX1262, no external PA, 22 dBm output)
+# - User button on D0 (P0.02)
+# - Optional SSD1306 0.96" OLED @ 0x3C on I2C1 (auto-detected)
+# - Battery ADC on AIN7 (P0.31), enable on P0.14
+# - LEDs: RED=P0.26, BLUE=P0.06, GREEN=P0.30
+#
+# Pin Mapping (XIAO D-pins to nRF52840 GPIOs):

+# - DIO2 drives the internal TX/RX antenna switch (dio2-tx-enable).
+# - RXEN (P0.05) is still wired on the PCB (shared trace across all three
+#   Stick variants) but has no external-PA function on this module — the
+#   line toggles are harmless.
